If we had 263 ml of mercury (volume) the density of the mercury is 13.55
g/cm”
Mass = Density x Volume (use image attached as guide)
Mass = 263 x 13.55 = 3563.65
Your mass should be 3563.65
Well theres no questions shown. So update your question
Gas chromatography (GC) is a method of separating mixed compounds.
The separation will depend on each compound's retention time. Compounds with
higher molecular weights will elute out slower than those with lower molecular
weight. This is due to their difference in boiling points. The larger the
structure, the higher the boiling point.

Answer:
The correct answer is option D. the adaptive immune system.
Explanation:
The adaptive immune system is the immune system that takes place after the first exposure to a specific antigen either from vaccination or a pathogen. Adaptive responses are of two types: the cell-mediated and humoral immune response, the cell-mediated immune response occurs with the help of T cells, and where is humoral immune response is B cells and antibodies.
Vaccination targets the adaptive immune system as they produce antibodies against the pathogen provided by vaccination.
Thus, the correct answer is option D. the adaptive immune system.
Answer: Option C.
Cellulose.
Explanation:
Cellulose is a polysaccharide which is made up of glucose and it is an important component in plant cell wall. It give strength and rigidity to the cell wall. Cellulose make the cell walls strong. This play a regulatory role in tissues growth and provide strength. The cellulose is only found in cell wall and it's protect the cell wall.
